We assume it as an ideal gas therefore we can use the ideal gas equation to solve the problem. The ideal gas equation is expressed as PV = nRT. We are given the volume, temperature and pressure. Therefore, we can solve for the amount of the gas in moles.

n = PV / RT

n = 1.00 (3L) / (0.08206 atm L/mol K) 273 K

n = 0.1339 mol
